The ability of listeners to distinguish between compound and phrasal stress in English was examined on the basis of a picture selection task. The responses to naturally and synthetically produced stimuli were compared. While greater overall accuracy was observed with the natural stimuli, the same pattern of greater accuracy with compound stress than with phrasal stress was observed with both types of stimuli.
